How much?

Randomly bouncing my way along the internet, I tripped over this site:

I dunno who made it or if anythings accurate on there, but it spurred an interesting question in my brain:

How much is the 2nd amendment worth?
In cash, that is.

Politics is about money. He who gives the most, oddly, gets the most.
The arguments dont matter. What counts is padding your politician with enough cash so he remembers to use them on your behalf.

They say we're currently paying 3 to 4 mil. According to these stats Casinos and tobacco are paying 10 to 15 mil, several times what we do. They seem to be progressing well despite the fact alot of people dont like em.
Insurance and oil look to get their way everywhere, but they put out over 40mil.
